I'm using Magento 2.3.0, and I'm trying to add a block before the
breadcrumbs, without any padding or margin.
I've created a block from the back-end, then my widget using this block, and then placed the widget on
Catalog Category, as I want it only on category pages, and as container I picked
After Page Header, but that places me the block/widget right after the
breadcrumbs, and it also has the padding from the block class, that I don't want, I would like to have it 100% width.
